Hi every one,
I am trying to solve below differential equation with matlab:
y''+(2/x)*y'=0.1248y
B.C 1 : y'(0)=0
B.C 2: y(1)=1
x interval: [0 1]
solution interval (or y): [0 1]
I used bvp4c and ode45 but every time I faced with error like "solve the collocation equations — a singular Jacobian encountered"
this is my code:
function SolveBVP()solinit = bvpinit([0,1],[0 0]);sol = bvp4c(@deriv,@bcs,solinit);x=linspace(0,1,100);y=deval(sol,x);plot(x,y(1,:),'b-x'); function dYdx = deriv(x,Y) dYdx(1) = Y(2); dYdx(2) = 0.1248*Y(1)-(2/x)*Y(2);function res = bcs(ya,yb)res = [ ya(2) yb(1)-1];
It would be appricated if any one of you can help me.
best regards
